Qld Maple again, this time i am trying a curved inside, not as easy as it looks with only a 1" gouge. I assume when i finally get a bowl gouge the tear out issues i am having will lessen?? This one was a bit easier as i learnt how the gouge behaves on the inside of the curve of the first one.
Sanded to 320grit.

yes that is a bird cage in the back ground, funny thing it turned out he was alergic to wood of all things and fell off the perch:;
piece stuck down with loads of CA and sacrificial pine screwed to face plate.
Bowl is 180x60.
Quick question, what are the streakes you can see in piccy 2 they seem to go away once wax is applied but wont sand away??
thanks.

They are called tear out or maybe scratches from previous grits.
They don't actually go away when you wax it. Have a look in sunlight and you will see them.:wink:
Tool technique and sharprness (bluntness?) is the main cause. Not removing the marks from the previous grit of sandpaper is the other.
I would be very wary of using CA. PVA or hot melt is a lot better in my opinion.
Good start though with the limits you have on you, i.e. tools and and self teaching.:D

P.S. be careful about screwing into end grain as well. Cross grain is much stronger.

I agree with , looks like and end grain waste / support block! :no: Another thought end grain to end grain glue joints are very weak & end grain to face grain not much better. Use a face grain waste block much much safer. :2tsup:
Very nice work on the bowl, you will get those marks out with practice and some encouragement from a tutor. :wink:

Got to waxing last night and yes today streaks are still visible, so back to the tools and paper. It's surprising what a dim workshop will hide:-
thanks for the pointers about glue and end grain etc. will be picking up a hot glue gun today and using the blocks side on. Would hardwood blocks be better as I have plenty of those laying around waiting for the fireplace.
cheers

I reckon with say a 12mm/1/2 bowl gouge and have sharp enough to shave with for your final cuts, much of your problem will be alleviated. I would suggest when you get your bowl gouge check how smooth finish is on the flute, ideally as smooth as a babies bum. Some are not that smooth and this effect your ability to produce a consistent edge.
If your struggling with sanding marks after that, maybe you need to look at the method
ie perhaps a inertia sander or a random orbital sander set up
